Senior Software Engineer (internationalization/localization)

Remitly Poland sp. z o.o. operates in the fintech industry, delivering global financial services to customers sending money worldwide. The company has over 2,800 employees globally and focuses on building secure, simple, and reliable money management solutions accessible across languages and countries.

• 6+ years of software development experience including internationalization/localization engineering and leading delivery of complex features.
• Strong programming skills in Golang, JavaScript, TypeScript, React Native, and modern web frameworks (Next.js, Astro) or comparable ecosystems (Java, Kotlin, C#/.NET).
• Experience applying AI/LLMs in production workflows, with judgment on automation versus human review; translation or content pipeline experience ideal.
• Working knowledge of internationalization standards and locale-aware formatting (Unicode, ICU/CLDR-based libraries).
• Proven ability to build or evolve localization systems and translation pipelines at scale.
• Experience with modern software development practices, code reviews, and secure coding standards.

Nice to have:

• Experience shipping RTL/bidirectional language support in production.
• Experience with localizability audits and pseudo-locale validation.
• Hands-on experience with TMS platforms (Lokalise, Phrase, Smartling, Transifex), ICU/CLDR internals, and localization interchange formats (XLIFF).
• Experience in fintech or another regulated industry.

• Own complex, team-level projects end-to-end: clarify requirements, break work into parallel tasks, and guide teammates toward on-time delivery.
• Build AI/LLM-powered translation and orchestration tooling: evaluate models, design quality guardrails, and integrate them into production localization pipelines.
• Build and maintain localization infrastructure, translation pipelines, and i18n tooling, integrated with translation management systems (TMS).
• Design CI/CD-integrated solutions for locale-specific rendering (currency, date/time, numeric formats), text extraction and translation workflows, and pseudo-locale validation.
• Standardize i18n frameworks and libraries across frontend and backend systems for correct handling of date/time, currency, pluralization, and message formatting.
• Build static code analysis and linting tooling to catch i18n defects before release, and harden existing code paths to eliminate recurring localization bugs.
• Expand Remitly's language coverage: right-to-left and bidirectional support, and transliteration tooling for accurate customer identity matching across scripts.
• Operate what you build: monitor, debug, and improve the reliability of your services, tooling, and translation pipelines in production.
• Partner across backend and frontend stacks with backend, mobile, web, and content teams, and mentor other engineers through code reviews and design discussions.
